Assertion : Gases do not liquefy above their critical temperature, even on applying high pressure. Reason : Above critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed.

Question

Assertion : Gases do not liquefy above their critical temperature, even on applying high pressure. Reason : Above critical temperature, the molecular speed is high and intermolecular attractions cannot hold the molecules together because they escape because of high speed., If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion., If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion., If the Assertion is correct but Reason is incorrect., If the Assertion is incorrect but the Reason is correct.

MARKS App · Accepted Answer

Gases do not liquefy above their critical temperature because as the temperature increases kinetic energy of the molecules also increases and it become difficult to liquefy them.
